我国从1956年起开始进行采矿下沉的观测和研究工作以来,逐步认识采矿地表移动和变形的规律,这为建筑物、铁路和水体下采煤能顺利进行打下良好的基础。现将我国二十多年来在采矿下沉方面的研究工作简要介绍如下。一、地表移动的基本参数为了解决保护地面建筑物、铁路及其构筑物免受采煤有害影响,必须掌握采矿下沉的一些主要参数。 (一) 移动角 Since the beginning of the observation and research on mining subsidence since 1956, China has gradually realized the law of surface movement and deformation in mining, which laid a good foundation for the smooth coal mining in buildings, railways and water bodies. At present, China’s research on mining subsidence for more than two decades is briefly described as follows. First, the basic parameters of surface movement In order to solve the protection of ground buildings, railways and their structures from the harmful effects of mining, we must grasp some of the main parameters of mining subsidence.
